7 Claims. (Cl. 40-120) This invention relates to a desk calendar and, more particularly, to a new and improved desk calendar of the rockable type.

An object of this invention is to provide a new and improved rockable desk calendar having a weight means for balancing the calendar in an upright position.

Another object of this invention is to provide a new and improved desk calendar of the rockable type including an upwardly-extending portion adapted to carry a calendar and advertising material, a base portion having arcuate supporting means and a metal rod rigidly secured within the base portion for balancing the calendar in an upright position.

Yet another object of this invention is to provide a new and improved desk calendar of the rockable type made of plastic and embodying a metal rod to balance the. calendar in an upright position and, more particularly,A to provide such a calendar made in two parts which are provided with recesses and abutments for receiving the rod and which hold the rod securely in place when the parts are secured together, said parts being secured together by plastic rivets extending from one part through counter-sunk holes in the other part and upset therein.'V

Other objects and advantages will become apparent from the following detailed description taken in connec-:

tion with the accompanying drawings, in which:

Fig. l is a front elevation of a desk calendar utilizing this invention;

Fig. 2 is a side elevation of the invention as shown in Fig. 1;

Fig. 3 is an exploded rear elevational view with the calendar carrying panel in a vertical plane, the back part being disconnected from the front part and rotated through 180;

Fig. 4 is an exploded vertical sectional view taken along line 4, 5 4, 5 of Fig. l; and

Fig. 5 is a fragmentary vertical sectional View taken along line 4, 5 4, 5 of Fig. 1.

While the invention herein described is a preferred embodiment, it is not intended to limit the invention to the specific form and arrangements shown, it being contemplated that various changes may be made by those skilled in the art without departing from the spirit and scope of the appended claims.

This invention is best shown in Figs. 1 and 2 wherein is shown a base or supporting portion 1 for the calendar and a at panel portion 2 extending substantially upwardly therefrom. Base portion lis generally cylindrical so as to permit rockable movement of the calendar. A metal rod or balance weight 3 is secured within base portion 1 so as to balance the calendar in a predetermined upright position. Panel portion 2 has an outwardly opening rectangular recess 4 in approximately the lower half thereof which is adapted to receive a calendar pad 5. The calendar pad 5 has a hole punched in each upper corner so that the calendar will fit on rivets 6 extending outwardly from each upper corner of recess 4. After the calendar 5 has been positioned on rivets 6, the rivets 4ICC are upset, thereby securing the calendar in the recess 4. Two projections 7 extend upwardly from the base of recess 4 and are spaced from the back face of recess 4. The lower unbound edges of the calendar pad 5 are adapted to be held in a flat position by being inserted between the rear face of recess 4 and projections 7. The remaining nonrecessed portion of panel 5 is especially well adapted for displaying advertising matter.

The embodiment of the invention illustrated and described herein comprises a desk calendar made of two molded plastic parts 8 and 9, it being understood that the invention is not limited to a calendar made of a particular material, as plastic, but includes calendars made of other materials such as metal wherein a balance member is rigidly secured in a rockable calendar when two parts thereof are secured together.

In the embodiment illustrated herein the front or supporting part 8 is generally cylindrical in shape and has circular end pieces 10 integral therewith adapted to rockably supportthe calendar on a at surface, as a desk. The extending panel portion 2 is integral with and extends from the supporting part 8. Two opposing lugs or abutments 11 extend longitudinally from the inner faces of circular end pieces 10. Lugs 11 are spaced so as to tightly receive therebetween balancing rod 3 to prevent endwise movement thereof. Also provided integral with supporting part 8 are three spaced cylindrically recessed brackets or projections 12. Brackets 12 are adapted to laterally receive balancing bar 3.

The clamping or rear molded plastic part 9 is generally semi-cylindrical in shape and is adapted to lit in mating engagement with supporting part 8. Extending laterally from the inner surface of rear part 9 are two cylindrically recessed brackets or projections 13 opposing brackets 12 on front part 8 and longitudinally spaced therefrom. When front part 8 and rear part 9 are secured together brackets 12 and 13 cooperate to laterally clamp balance bar 3 in a rigid position.

Front part 8 has three horizontally aligned countersunk holes 14 extending through the at panel portion 2- Three plastic rivets 15 integral with rear or clamping part 9 extend laterally from the inner surface thereof. Rivets 15 are positioned so as to be in alignment with holes 14 when supporting part 8 and clamping part 9 are secured together. Each rivet 15 has an end portion 16 of decreased diameter which is adapted to extend through an associated hole 14 when supporting part 8 and clamping part 9 are in mating engagement. With balancing bar 3 positioned between the two plastic parts 8 and 9 in brackets 12 and 13, the end portions 16 of rivets 15 are upset in countersunk holes 14 at normal room temperature, as at 17 in Figs. l and 5, thus, tightly securing the two plastic parts of the calendar together.

It is believed apparent that it has been shown that applicant has developed a rockable desk calendar having a metal balancing rod rigidly secured thereto laterally and longitudinally without the use of adhesives or mechanical devices. In this calendar, the balancing rod is tightly secured between two mating parts, one of which has a series of rivets integral therewith and adapted to be upset in a series of mating countersunk holes in the other part to secure the two together. As the coecients of expansion of both mating parts are the same, applicant has thus provided a solution to the problem of rigidly securing a metal balancing rod to a rockable calendar Without the connection therebetween being adversely affected by any extreme temperatures encountered during shipment or at other times, which possibility is very likely where a metal balancing rod is directly connected to another part, especially a plastic part, as by adhesives or mechanical devices.

I claim:
